Thu, 23 Jul 2015 06:01:20 +0000http://rayshobby.net/?p=10241#comment-119009I have a ESP8266-1 , which stopped working and I cant install a boot loader in it. It also seems to get hot snf I could not communicate with it. I did some tests & found that the RX line is shorted to Ground somewhere under the ESP8266/MCU (not under the EEPROM which I could remove OK.
Removing the 8266/MCU is just too hard, so in the bin it goes.
FWIIW , as far as the ballast resistors on the LEDS, the RED led has a 2.2 K & the BLUE has a 4.7K

I’m quite new to arduino and esp8266. Currently I’m trying a simple thing – connect arduino UNO to wifi network using ESP8266 and read a webpage from the internet.

I’m using the AT firmware on ESP8266. I can connect it to wifi and open a TCP connection to web server, pass the URL I want to receive, but I have the following problem:

This gives me exactly what I need to my debug console – the whole HTTP response together with the content. The moment I comment out the debug output to soft serial, I only get very little data from the server. When I add a delayMicroseconds(50) after Serial.read(), I get a little more data to strReceived, but never as much as when I use the serial debug.
